I tried Optimum Nutritious Mass, and it has quickly become my go-to for gaining muscle mass. The taste is great, mixing easily with water or milk without any clumps. I’ve noticed significant gains in muscle and energy levels since incorporating it into my routine. Highly recommend for anyone looking to bulk up effectively!

I had ordered the same but in vanilla, it was

I had ordered the same but in vanilla, it was absolutely revolting and it smelled and tasted like a bunch of chemicals I really tried to convince myself it wasn’t that bad but no matter what i mixed it with it was terrible hence why i switched to the strawberry and it tastes amazing, it tastes just like the strawberry nesquick or like a strawberry milkshake. It doesn’t smell chemically at all despite the many reviews where it says it does and in my opinion it’s the best flavour out of all of them and i think it’s a lot easier to drink if you’re not too keen on using enhancing products like serious mass since you’ll actually enjoy the taste and personally it motivated me to drink it more often and stick to it.

I have ridiculous metabolism... these drinks are literally the only thing that can make me fat, I got up to 12.5st last year! Which is unheard of for me, I already have good muscle tone and wasnt working out with this drink, simply wanted to put some fat on, and i did, very quickly.
